GHSA-whhr-7f2w-qqj2
HIGHphonenumber panics on parsing crafted RFC3966 inputs
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
phonenumber🦀phonenumberReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
Impact
The phonenumber parsing code may panic due to a panic-guarded out-of-bounds access on the phonenumber string.
In a typical deployment of rust-phonenumber, this may get triggered by feeding a maliciously crafted phonenumber over the network, specifically the string .;phone-context=.
Patches
Patches will be published as version 0.3.3+8.13.9 and backported as 0.2.5+8.11.3.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for phonenumber. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update phonenumber to 0.2.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-whhr-7f2w-qqj2 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-whhr-7f2w-qqj2 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-whhr-7f2w-qqj2. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-whhr-7f2w-qqj2 in your dependencies?
O3 detects GHSA-whhr-7f2w-qqj2 across crates.io dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
